Description

Touch sensing unit and display device including the same

This application claims priority and benefit from korean patent application No. 10-2018-0112038, filed by the korean intellectual property office at 19.9.2018, the disclosure of which is incorporated herein by reference in its entirety.

Technical Field

The present disclosure relates to a display device, and more particularly, to a touch sensing unit and a display device including the same.

Background

Display devices have been incorporated into a variety of different electronic systems, some of which are portable (such as smart phones) and others of which are stationary (such as televisions and computer monitors). In many of these systems, it is desirable to have a relatively large display area and a minimal bezel surrounding the display area. One way to characterize this property is to describe a screen-to-body ratio (also known as screen-to-body ratio), with larger screen-to-body ratios being most desirable. In some devices (such as smart phones), various modules such as speakers and optical sensors are disposed on the front side of the device. Although these modules may be disposed outside the display screen, in order to increase the screen-to-body ratio, these modules may be disposed in a groove shape or a groove shape that has been removed from the shape of the display screen.

Many devices, such as smart phones, may use a touch screen display that is capable of not only displaying images but also sensing a user's touch. These touch screens may include a touch member disposed over a display panel. The touch member is a sensor device that may be configured to identify the location of a touch event (such as the touch of a finger or stylus), and even the degree of pressure that has been so applied.

The touch member may sense touch events using one or more different methods. Examples of these methods may include a resistive film type method, a light sensing method, or a capacitance method.

Detailed Description

The features of the inventive concept and methods of accomplishing the same may be understood more readily by reference to the following detailed description of the embodiments and the accompanying drawings. The inventive concept may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the inventive concept to those skilled in the art.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the inventive concept. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It will be understood that when an element or layer is referred to as being "on," "connected to" or "coupled to" another element or layer, it can be directly on, connected or coupled to the other element or layer or intervening elements or layers may be present.

It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the inventive concept.

A display device according to various exemplary embodiments of the present disclosure is a device for displaying moving or still, two-dimensional or stereoscopic images. The display apparatus may be used in mobile electronic devices, such as mobile communication terminals, smart phones, tablets, smart watches, and navigation devices, and may also be used in various other non-mobile products, such as Televisions (TVs), laptops, monitors, billboards, or internet of things (IoT) devices.

Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the accompanying drawings. In the following description, the organic light emitting display device will be described as an exemplary display device, but the present disclosure is not limited thereto. For example, the inventive concepts of the present disclosure are also applicable to other display devices, such as a Liquid Crystal Display (LCD) device, a Field Emission Display (FED) device, an electrophoretic display (EPD) device, a quantum dot light emitting diode (QLED) display device, or a micro light emitting diode (mLED) display device. In the drawings, the same (or similar) reference numerals may denote the same elements.

Fig. 1 is a plan view illustrating an organic light emitting display device according to an exemplary embodiment of the present disclosure. Fig. 2 is a partial sectional view of the organic light emitting display device of fig. 1.

Referring to fig. 1, the organic light emitting display device 1 includes a display area DA and a non-display area NDA.

The display area DA is defined as an area where an image is displayed. The organic light emitting display device 1 may include a plurality of pixels disposed in the display area DA. The display area DA may be an area for displaying an image and may also be an area for recognizing a touch input or a fingerprint from a user. In one exemplary embodiment of the present disclosure, the display area DA may have a partially recessed edge (e.g., an upper edge in the example of fig. 1). For example, one edge of the display area DA in the first direction dr1 may be formed in an irregular shape to have a notch, groove, or groove shape in a plan view. Here, the irregular edge of the display area DA may include two convex portions protruding outward from the display area DA and a concave portion recessed into the display area DA.

As used herein, the vertical direction of a drawing such as that of fig. 1 will be defined as a first direction dr1, and the direction intersecting the first direction dr1 will be defined as a second direction dr 2. For example, the second direction dr2 may correspond to a horizontal direction of a drawing such as fig. 1. However, the present disclosure is not limited thereto. In contrast, the first direction dr1 and the second direction dr2 should be understood as opposite directions crossing each other. For convenience, in the drawings, the upper side, the lower side, the left side and the right side will be defined as a first side in the first direction dr1, a second side in the first direction dr1, a first side in the second direction dr2 and a second side in the second direction dr2, respectively, but should be understood as relative positions. As shown in fig. 1, the first direction dr1 and the second direction dr2 can be perpendicular with respect to each other, but this need not be the case, as they can optionally intersect at an angle other than a right angle.

In one exemplary embodiment of the present disclosure, the display area DA may include a first display area DA1 and second and third display areas DA2 and DA3, the second and third display areas DA2 and DA3 protruding from the first display area DA1 toward a first side in the first direction dr 1. The second display region DA2 may be a region disposed at the upper left corner of the first display region DA1, and the third display region DA3 may be a region disposed at the upper right corner of the first display region DA 1. The second display area DA2 and the third display area DA3 may be spaced apart from each other in the second direction dr 2.

Two convex portions of the irregular edge of the display area DA may be formed by the second display area DA2 and the third display area DA 3. Further, the recessed portion of the display area DA may be formed by an upper edge of a portion of the first display area DA1 between the second display area DA2 and the third display area DA 3.

The non-display area NDA is defined as an area where no image is displayed. The non-display area NDA may at least partially surround the display area DA. For example, the non-display area NDA may at least partially surround one or more of the first to third display areas DA1 to DA 3.

In one exemplary embodiment of the present disclosure, the non-display area NDA may have a substantially rectangular shape with rounded corners, but the present disclosure is not limited thereto. The non-display area NDA may include a central area, which is a portion of the non-display area NDA located between the second display area DA2 and the third display area DA 3. The non-display area NDA may include a rectangular frame having rounded corners and a protruding portion formed by the second display area DA2 and the third display area DA3 to intrude into the display area DA.

The speaker module MD1, the camera module MD2, and the sensor module MD3 may be disposed in a portion of the non-display area NDA. In one exemplary embodiment of the present disclosure, the speaker module MD1, the camera module MD2, and the sensor module MD3 may be disposed in an upper portion of a center region of the non-display region NDA near an upper edge of the non-display region NDA. As will be described later, various wirings bypassing the speaker module MD1, the camera module MD2, and the sensor module MD3 may pass through the protruding portion of the non-display area NDA. In an exemplary embodiment of the present disclosure, the sensor module MD3 may include an illuminance sensor, a proximity sensor (also referred to as a distance sensor), an infrared sensor, and/or an ultrasonic sensor. The arrangement of the speaker module MD1, the camera module MD2, and the sensor module MD3 is not particularly limited.

Referring to fig. 2, in one exemplary embodiment of the present disclosure, the organic light emitting display device 1 may include a substrate 10, a circuit layer 20 disposed on the substrate 10, a light emitting layer 30 disposed on the circuit layer 20, an encapsulation layer 40 disposed on the light emitting layer 30, a touch layer 50 disposed on the encapsulation layer 40, and a cover layer 60 disposed on the touch layer 50, but the present disclosure is not limited thereto. Each layer of the organic light emitting display device 1 may have a multi-layer or single-layer structure. Further, some of the layers of the organic light emitting display device 1 may be omitted, or other layers may be newly added to the organic light emitting display device 1. The stack structure of the organic light emitting display device 1 will be described later with reference to fig. 7 and 8.

The touch layer 50 may include a touch sensing unit that senses a touch input from a user. Hereinafter, the arrangement of elements of the touch layer 50 will be described with reference to fig. 3 and 4.

Fig. 3 is a schematic layout diagram showing a layout of the touch sensing unit. Fig. 4 is a schematic plan view showing each region on the substrate. Fig. 5 is a layout view illustrating the detection electrode unit of fig. 3. Fig. 6 is an enlarged view showing a region FF of fig. 3.

Referring to fig. 3 to 6, the touch sensing unit 50a includes a touch member, a pad (may also be referred to as "pad") terminal unit TPA, and a base on which the touch member and the pad terminal unit TPA are disposed. The touch member includes sensing electrode elements IE1 and IE2 and a signal wiring element connected to the sensing electrode elements IE1 and IE 2. The signal wiring unit may be disposed in the non-sensing area NAA, and may at least partially surround the detection electrode units IE1 and IE 2. Various features of the non-sensing area NAA of the signal wiring unit may be exaggerated in fig. 3 to 6 for convenience of explanation.

The base may be a layer on which the touch member and the pad terminal unit TPA are disposed. In one exemplary embodiment of the present disclosure, the substrate may be an encapsulation layer 40. In an exemplary embodiment of the present disclosure, the organic light emitting display device 1 may further include a touch substrate on which the touch member and the pad terminal unit TPA are disposed, and the touch substrate may be referred to as a substrate.

The substrate may include a plurality of regions, and at least two of the regions may have areas of different sizes. The shape of the substrate may be substantially the same as that of the organic light emitting display device 1. In an exemplary embodiment of the present disclosure, the sensing area AA and the non-sensing area NAA at least partially surrounding the sensing area AA may be defined on the base. The sensing areas AA may include first to third sensing areas AA1 to AA 3.

The shape of the sensing area AA may be substantially the same as the shape of the display area DA. The sensing area AA may include an irregular edge partially recessed into the sensing area AA. The shapes of the first to third sensing regions AA1 to AA3 may be the same as the shapes of the first to third display regions DA1 to DA3, respectively. For example, the sensing area AA may include a first sensing area AA1 and second and third sensing areas AA2 and AA3, the second and third sensing areas AA2 and AA3 protruding from the first sensing area AA1 toward the first side in the first direction dr 1. The second sensing area AA2 and the third sensing area AA3 may at least partially overlap each other in the second direction dr 2.

The non-sensing area NAA may surround the first to third sensing areas AA1 to AA3 and may have substantially the same shape as that of the non-display area NDA. The non-sensing area NAA may include a central area CA disposed between the second and third sensing areas AA2 and AA3 in the second direction dr2 and overlapping the second and third sensing areas AA2 and AA 3.

The detection electrode elements IE1 and IE2 may include a plurality of first touch detection electrodes IE1 extending in the first direction dr1 and a plurality of second touch detection electrodes IE2 intersecting at least one of the first touch detection electrodes IE 1. The second touch detection electrode IE2 may extend in the second direction dr 2. In one exemplary embodiment of the present disclosure, the detection electrode elements IE1 and IE2 may be disposed in the sensing region AA, but the present disclosure is not limited thereto.

Detection electrode elements IE1 and IE2 may include sensing electrodes and drive electrodes. As used herein, the term "detection electrode unit" or "detection electrode" may refer to both the sensing electrode and the driving electrode together. In the exemplary embodiments of fig. 3 to 6, the first touch detection electrode IE1 may be a driving electrode and the second touch detection electrode IE2 may be a sensing electrode.

The first touch detection electrode IE1 may include five driving electrodes, i.e., a first driving electrode TE1 to a fifth driving electrode TE5, and the second touch detection electrode IE2 may include nine sensing electrodes, i.e., a first sensing electrode RE1 to a ninth sensing electrode RE 9. However, the number of the first and second touch detection electrodes IE1 and IE2 is not particularly limited.

The first touch detection electrode IE1 may extend in the first direction dr1, and the second touch detection electrode IE2 may extend in the second direction dr 2. In one exemplary embodiment of the present disclosure, the length of the first touch detection electrode IE1 in the first direction dr1 may be greater than the length of the second touch detection electrode IE2 in the second direction dr2, in which case the organic light emitting display device 1 may be longer in the first direction dr1 than in the second direction dr 2.

In one exemplary embodiment of the present disclosure, the first touch detection electrode IE1 may include: a first driving electrode TE1 extending from the second sensing region AA2 toward the second side in the first direction dr 1; a fifth driving electrode TE5 extending from the third sensing area AA3 toward the second side in the first direction dr 1; and a second driving electrode TE2, a third driving electrode TE3, and a fourth driving electrode TE4 disposed between the first driving electrode TE1 and the fifth driving electrode TE 5. The first and fifth driving electrodes TE1 and TE5 may extend from the second and third sensing regions AA2 and AA3 to the first sensing region AA1, respectively.

The first touch detection electrodes IE1 may be disposed adjacent to and spaced apart from each other in the second direction dr 2. For example, the first to fifth driving electrodes TE1 to TE5 may be sequentially arranged in the second direction dr2 and may be spaced apart from each other. The first and fifth driving electrodes TE1 and TE5 may be disposed adjacent to first and second edges of the sensing area AA in the second direction dr2, respectively.

The first touch detection electrode IE1 may include drive electrodes having different lengths in the first direction dr 1. For example, the lengths in the first direction dr1 of the first and fifth driving electrodes TE1 and TE5 extending from the second and third sensing areas AA2 and AA3 to the first sensing area AA1 may be greater than the lengths in the first direction dr1 of the second to fourth driving electrodes TE2 to TE4 extending only in the first sensing area AA 1.

Each of the driving electrodes may include at least one driving detection pattern. For example, each of the first and fifth driving electrodes TE1 and TE5 may include first to ninth driving detection patterns TE11 to TE19 or first to ninth driving detection patterns TE51 to TE59, first to ninth driving detection patterns TE11 to TE19 or first to ninth driving detection patterns TE51 to TE59 sequentially arranged in the first direction dr1 and may be spaced apart from each other. Each of the second to fourth driving electrodes TE2 to TE4 may include first to eighth driving detection patterns TE21 to TE28, first to eighth driving detection patterns TE31 to TE38, or first to eighth driving detection patterns TE41 to TE48 which are sequentially arranged in the first direction dr1 and may be spaced apart from each other.

The first driving detection pattern TE11 of the first driving electrode TE1 and the first driving detection pattern TE51 of the fifth driving electrode TE5 may be disposed in the second and third sensing areas AA2 and 3, respectively, and thus, may not overlap the second to fourth driving electrodes TE2 to TE4 in the second direction dr 2. The second to ninth driving sensing patterns TE12 to TE19 of the first driving electrode TE1 and the second to ninth driving sensing patterns TE52 to TE59 of the fifth driving electrode TE5 may overlap at least partially with the first to eighth driving sensing patterns TE21 to TE28 of the second driving electrode TE2, the first to eighth driving sensing patterns TE31 to TE38 of the third driving electrode TE3 and the first to eighth driving sensing patterns TE41 to TE48 of the fourth driving electrode TE4 in the second direction dr 2. In one exemplary embodiment of the present disclosure, the second driving detection pattern TE12 of the first driving electrode TE1 may be disposed in the first and second sensing areas AA1 and AA2 and may include a boundary between the first and second sensing areas AA1 and 2, and the second driving detection pattern TE52 of the fifth driving electrode TE5 may be disposed in the first and third sensing areas AA1 and AA3 and may include a boundary between the first and third sensing areas AA1 and AA 3. The first and fifth driving electrodes TE1 and TE5 may have a region where they overlap with the second to fourth driving electrodes TE2 to TE4 in the second direction dr2 and a region where they do not overlap with the second to fourth driving electrodes TE2 to TE4 in the second direction dr 2. The first and fifth driving electrodes TE1 and TE5 may at least partially overlap each other in the second direction dr2 in a region where they do not overlap the second to fourth driving electrodes TE2 to TE 4.

The second touch detection electrode IE2 may include: a first sub-touch detection electrode element IE2a continuously extending from a first edge to a second edge of the first sensing area AA1 in the second direction dr2 along the second direction dr 2; and a second sub touch detection electrode element IE2b disposed in the second and third sensing areas AA2 and AA 3. Each of the first sub-touch detection electrode element IE2a and the second sub-touch detection electrode element IE2b may include at least one sensing electrode. In one exemplary embodiment of the present disclosure, the first sub-touch detection electrode element IE2a may include first through seventh sensing electrodes RE1 through RE7, and the second sub-touch detection electrode element IE2b may include eighth and ninth sensing electrodes RE8 and RE 9.

The first to seventh sensing electrodes RE1 to RE7 of the first sub-touch detection electrode unit IE2a may be disposed adjacent to and spaced apart from each other in the first direction dr 1. For example, the first to seventh sensing electrodes RE1 to RE7 of the first sub-touch detection electrode unit IE2a may be sequentially arranged in the first direction dr1 and may be spaced apart from each other.

The second sub-touch detection electrode element IE2b may be disposed adjacent to the first sub-touch detection electrode element IE2a in the first direction dr 1. In one exemplary embodiment of the present disclosure, the eighth and ninth sensing electrodes RE8 and RE9 of the second sub touch detection electrode element IE2b may be adjacent to and spaced apart from a first side of the first sensing electrode RE1 in the first direction dr 1.

In one exemplary embodiment of the present disclosure, the first to seventh sensing electrodes RE1 to RE7 may have the same length in the second direction dr 2. The first sub-touch detection electrode element IE2a and the second sub-touch detection electrode element IE2b may have different lengths in the second direction dr 2. For example, the length of the first sub-touch detection electrode element IE2a in the second direction dr2 may be greater than the length of the second sub-touch detection electrode element IE2b in the second direction dr 2.

The second sub-touch detection electrode element IE2b may have the same shape as that obtained by removing the middle portion of the first sensing electrode RE 1. For example, the second sub-touch detection electrode element IE2b may have the same shape as the combined shape of both end portions of the first sensing electrode RE 1.

The second sub-touch detection electrode element IE2b may include: an eighth sensing electrode RE8 disposed in the second sensing region AA 2; and a ninth sensing electrode RE9 disposed in the third sensing region AA 3. The eighth and ninth sensing electrodes RE8 and RE9 may be disposed on the same imaginary straight line extending in the second direction dr 2. For example, the eighth sense electrode RE8 and the ninth sense electrode RE9 may be spaced apart from each other and at least partially overlap each other in the second direction dr 2.

Each of the first to ninth sensing electrodes RE1 to RE9 may include at least one sensing detection pattern. For example, each of the first to seventh sensing electrodes RE1 to RE7 may include first to sixth sensing patterns RE11 to RE16, first to sixth sensing patterns RE21 to RE26, first to sixth sensing patterns RE31 to RE36, first to sixth sensing patterns RE41 to RE46, first to sixth sensing patterns RE51 to RE56, first to sixth sensing patterns RE61 to RE66, or first to sixth sensing patterns RE71 to RE76, which are sequentially arranged in the second direction dr 2. Each of the eighth and ninth sensing electrodes RE8 and RE9 may include first and second sensing detection patterns RE81 and RE82 or first and second sensing detection patterns RE91 and RE92, the first and second sensing detection patterns RE81 and RE82 being spaced apart from the first and second sensing detection patterns RE91 and RE 92. The first and second sensing detection patterns RE81 and RE82 of the eighth sensing electrode RE8 may have areas of different sizes. The area of the first sensing detection pattern RE81 of the eighth sensing electrode RE8 may be greater than the area of the second sensing detection pattern RE82 of the eighth sensing electrode RE 8. Similarly, the first and second sensing detection patterns RE91 and RE92 of the ninth sensing electrode RE9 may have areas of different sizes. The area of the first sensing detection pattern RE91 of the ninth sensing electrode RE9 may be smaller than the area of the second sensing detection pattern RE92 of the ninth sensing electrode RE 9.

Each pair of sensing detection patterns adjacent in the second direction dr2 may be physically connected via a connection CP. The connection part CP may pass between each pair of adjacent driving detection patterns so that each pair of adjacent driving detection patterns may be physically separated. For example, the first and second sensing detection patterns RE11 and RE12 of the first sensing electrode RE1 may be physically connected via the connection part CP, but the second and third driving detection patterns TE12 and TE13 of the first driving electrode TE1 may be physically separated due to the connection part CP. Pairs of adjacent drive detection patterns may BE electrically connected via bridge electrodes BE1 and BE 2.

The first and second sensing detection patterns RE81 and RE82 of the eighth sensing electrode RE8 may be physically connected to each other, and may pass between the first and second driving detection patterns TE11 and TE12 of the first driving electrode TE1 to physically separate the first and second driving detection patterns TE11 and TE12 of the first driving electrode TE 1. Similarly, the first and second sensing detection patterns RE91 and RE92 of the ninth sensing electrode RE9 may be physically connected to each other and may pass between the first and second driving detection patterns TE51 and TE52 of the fifth driving electrode TE5 to physically separate the first and second driving detection patterns TE51 and TE52 of the fifth driving electrode TE 5. The second sensing detection pattern RE82 of the eighth sensing electrode RE8 and the first sensing detection pattern RE91 of the ninth sensing electrode RE9 may be disposed between the first driving electrode TE1 and the fifth driving electrode TE 5.

The eighth sensing electrode RE8 may extend through the first driving electrode TE1, but not through the second through fifth driving electrodes TE2 through TE 5. The ninth sensing electrode RE9 may extend through the fifth driving electrode TE5, but not through the first to fourth driving electrodes TE1 to TE 4. The first to seventh sense electrodes RE1 to RE7 may extend through all of the drive electrodes TE1 to TE 5.

In one exemplary embodiment of the present disclosure, the detection patterns disposed between a pair of detection patterns at both ends of each of the first and second touch detection electrodes IE1 and IE2 may have a diamond shape. The pair of detection patterns at both ends of each of the first and second touch detection electrodes IE1 and IE2 may have the shape of an equilateral triangle obtained by cutting a diamond in half. Each of the driving detection patterns TE11 to TE59 and each of the sensing detection patterns RE11 to RE92 may have at least one side formed in a zigzag shape. For example, the second driving detection pattern TE12 having a diamond shape and the second sensing detection pattern RE12 also having a diamond shape may have all sides formed in a zigzag shape. For example, the first driving detection pattern TE11 having an equilateral triangle shape and the first sensing detection pattern RE11 also having an equilateral triangle shape may have two sides formed in a zigzag shape and the other sides formed as straight lines. In the case where each of the driving detection patterns TE11 to TE59 and each of the sensing detection patterns RE11 to RE92 include sides of a zigzag shape, moir é can be prevented, and display defects that may be caused to the organic light emitting display device 1 by the moir é can be prevented.

There may be a gap between the first touch detection electrode IE1 and the second touch detection electrode IE 2. The first and second touch detection electrodes IE1 and IE2 may be spaced apart and insulated from each other by a gap. The gap may refer to a space formed between the first and second touch detection electrodes IE1 and IE2 that are physically separated from each other. An insulating material may be disposed in the gap.

Referring to fig. 6, in each first touch detection electrode IE1 (e.g., in the first drive electrode TE 1), a pair of bridge electrodes BE1 and BE2 may electrically connect a pair of adjacent drive detection patterns (e.g., the second drive detection pattern TE12 and the third drive detection pattern TE13) in the first direction dr 1. The bridge electrodes BE1 and BE2 may connect the corners of the second driving sensing pattern TE12 with the corners of the third driving sensing pattern TE 13.

The bridge electrodes BE1 and BE2 may extend through one second touch detection electrode IE 2. For example, the bridge electrodes BE1 and BE2 may include a portion overlapping one second touch detection electrode IE2 (e.g., first sensing electrode RE 1). The bridge electrodes BE1 and BE2 may BE insulated from the first sense electrode RE 1.

A first touch insulating layer 511 (see, e.g., fig. 7 and 8) may BE included between the bridge electrodes BE1 and BE2 and the first sense electrode RE1 and the first drive electrode TE 1. The first touch insulating layer 511 may BE disposed on the bridge electrodes BE1 and BE2, and in this case, the first touch insulating layer 511 may include a plurality of contact holes CNT exposing portions of the bridge electrodes BE1 and BE2 at or near the first and second ends of the bridge electrodes BE1 and BE 2. The contact hole CNT may at least partially overlap the first driving electrode TE 1. The first driving electrode TE1 may BE physically connected to the bridge electrodes BE1 and BE2 via contact holes CNT. Accordingly, a pair of adjacent driving detection patterns (e.g., the second driving detection pattern TE12 and the third driving detection pattern TE13) in the first driving electrode TE1 may be electrically connected.

First ends of the bridge electrodes BE1 and BE2 may extend in the third direction, and second ends of the bridge electrodes BE1 and BE2 may extend in the fourth direction. In one exemplary embodiment of the present disclosure, the third and fourth directions may be directions inclined with respect to the first and second directions dr1 and dr2, but the present disclosure is not limited thereto. The third direction and the fourth direction may be symmetrical to each other with respect to an imaginary center line extending in the second direction dr 2. For example, the bridge electrodes BE1 and BE2 may BE provided in a curved shape, such as a shape of "<" or ">". In an exemplary embodiment of the present disclosure, the third direction may be the first direction dr1 extending upward, and the fourth direction may be the first direction dr1 extending downward. In this exemplary embodiment of the present disclosure, the bridge electrodes BE1 and BE2 may have a straight line shape. In exemplary embodiments of the present disclosure, the bridge electrodes BE1 and BE2 may have non-angled corners and may BE provided in a curved shape having non-angled corners, such as a "(" or ")" shape.

At least one bridge electrode may be provided to connect the second and third driving sensing patterns TE12 and TE13 of the first driving electrode TE1 to each other. In one exemplary embodiment of the present disclosure, two bridge electrodes BE1 and BE2 may BE provided to connect the second driving sensing pattern TE12 with the third driving sensing pattern TE 13. In this exemplary embodiment of the present disclosure, even if one of the two bridge electrodes BE1 and BE2 is disconnected, the second drive check pattern TE12 and the third drive check pattern TE13 may remain electrically connected due to the other bridge electrode. The two bridge electrodes BE1 and BE2 may BE symmetrical to each other with respect to an imaginary center line extending in the first direction dr 1.

In each of the second touch detection electrodes IE2 (e.g., in the first sense electrode RE1), the connection portion CP may be disposed between a pair of adjacent sense detection patterns (e.g., the first sense detection pattern RE11 and the second sense detection pattern RE12) and may also be disposed between a pair of adjacent drive detection patterns (e.g., the second drive detection pattern TE12 and the third drive detection pattern TE13 of the first drive electrode TE1, which are adjacent to and separated from each other).

The pair of adjacent driving detection patterns in each first touch detection electrode IE1 and the pair of adjacent sensing detection patterns in each second touch detection electrode IE2 may form a cell sensing region SUT. For example, in a region where one first touch detection electrode IE1 and one second touch detection electrode IE2 cross each other, half of a pair of adjacent driving detection patterns in the second direction dr2 (e.g., half of the second driving detection pattern TE22 of the second driving electrode TE2 and half of the second driving detection pattern TE32 of the third driving electrode TE 3) and half of a pair of adjacent sensing detection patterns in the first direction dr1 (e.g., half of the third sensing detection pattern RE13 of the first sensing electrode RE1 and half of the third sensing detection pattern RE23 of the second sensing electrode RE 2) may form a single unit sensing region SUT having a square or rectangular shape. The cell sensing regions SUT may be arranged in a row direction and a column direction.

The unit sensing regions SUT may detect a touch input by measuring capacitances between the pair of adjacent driving detection patterns and the pair of adjacent sensing detection patterns, and may calculate a position of the detected touch input as touch input coordinates. The cell sensing area SUT may detect a touch input in a mutual capacitance manner, but the present disclosure is not limited thereto.

The cell sensing area SUT may be larger in size than the pixel. For example, a single sensing unit region SUT may correspond to a plurality of pixels. The cell sensing area SUT may have a length of 4mm to 5mm, but the present disclosure is not limited thereto.

The dummy electrode DE may be disposed between the first and second touch detection electrodes IE1 and IE 2. The dummy electrode DE may be formed during the formation of the first and second touch detection electrodes IE1 and IE 2. The first and second touch detection electrodes IE1 and IE2 may be formed by being separated from a single electrode. For example, conductive electrodes may be etched into a first touch detection electrode IE1 and a second touch detection electrode IE 2. During the etching of the conductive electrode, a dummy electrode DE may be formed between the first and second touch detection electrodes IE1 and IE2 to control an area of a driving detection pattern of each first touch detection electrode IE1 and an area of a sensing detection pattern of each second touch detection electrode IE 2. The first touch detection electrode IE1, the second touch detection electrode IE2, and the dummy electrode DE may be physically separated from each other via etching, and the aforementioned gap may exist between the first touch detection electrode IE1, the second touch detection electrode IE2, and the dummy electrode DE. In other exemplary embodiments of the present disclosure, the dummy electrode DE may be omitted.

The touch member includes a signal wiring unit disposed in the non-display area NDA. The signal wiring unit may include touch driving wirings TX1_1 to TX5_1 and TX1_2 to TX5_2, touch sensing wirings RX1_1 to RX8_1 and RX1_2, guard wirings GL1 to GL5, and antistatic wirings ES1 and ES 2. The touch driving wirings TX1_1 to TX5_1 and TX1_2 to TX5_2, the touch sensing wirings RX1_1 to RX8_1 and RX1_2, the shield wirings GL1 to GL5, and the anti-static wirings ES1 and ES2 may extend from the pad terminal unit TPA to the non-display area NDA, and the touch driving wirings TX1_1 to TX5_1 and TX1_2 to TX5_2 and the touch sensing wirings RX1_1 to RX8_1 and RX1_2 may be connected to the first touch detection electrode IE1 and the second touch detection electrode IE 2.

The driving signals may be transmitted to the first touch detection electrode IE1 via the touch driving wirings TX1_1 to TX5_1 and TX1_2 to TX5_2, and the sensing signals may be transmitted to the second touch detection electrode IE2 via the touch sensing wirings RX1_1 to RX8_1 and RX1_ 2.

The touch driving wirings TX1_1 to TX5_1 and TX1_2 to TX5_2 may be connected to the first touch detection electrode IE 1. In one exemplary embodiment of the present disclosure, a plurality of touch driving wirings may be connected to a single first touch detection electrode IE 1. For example, the touch driving wirings TX1_1 to TX5_1 and TX1_2 to TX5_2 may include first touch driving wirings TX1_1 to TX5_1 connected to a lower end of the first touch detection electrode IE1 and second touch driving wirings TX1_2 to TX5_2 connected to an upper end of the first touch detection electrode IE 1.

In one exemplary embodiment of the present disclosure, the first touch driving wirings TX1_1 to TX5_1 may extend from the pad terminal unit TPA toward the first side and/or the second side in the second direction dr2 to be connected to the lower end of the first touch detection electrode IE 1.

In one exemplary embodiment of the present disclosure, the second touch driving wirings TX1_2 to TX5_2 may extend from the pad terminal unit TPA toward the first side in the second direction dr2, may bypass the left edge of the display area DA, and may bypass the upper edge of the display area DA including the protruding portion to be connected to the upper end of the first touch detection electrode IE 1.

In one exemplary embodiment of the present disclosure, at least some of the second touch driving wirings TX1_2 to TX5_2 may bypass an area in which the speaker module MD1, the camera module MD2, and the sensor module MD3 are disposed while bypassing the upper edge of the display area DA. For example, the second touch driving wirings TX1_2 to TX5_2 connected to the first to fifth driving electrodes TE1 to TE5 may generally extend in the second direction dr2 while bypassing the upper edge of the display area DA, but may include a portion extending in the first direction dr1 to bypass an area in which the speaker module MD1, the camera module MD2, and the sensor module MD3 are disposed.

The second touch driving wirings TX2_2 to TX4_2 connected to the second to fourth driving electrodes TE2 to TE4 may include a portion disposed between the eighth and ninth sensing electrodes RE8 and RE 9. For example, the second touch driving wirings TX2_2 to TX4_2 connected to the second to fourth driving electrodes TE2 to TE4 may pass through the central area CA. The second touch driving wirings TX2_2 to TX4_2 connected to the second to fourth driving electrodes TE2 to TE4 may include portions overlapping the eighth and ninth sensing electrodes RE8 and RE9 in the second direction dr 2.

The touch sensing wirings RX1_1 to RX8_1 and RX1_2 are connected to the second touch detection electrode IE 2. In one exemplary embodiment of the present disclosure, unlike the first to fifth driving electrodes TE1 to TE5, each of the first to ninth sensing electrodes RE1 to RE9 may be connected to one of the touch sensing wirings RX1_1 to RX8_1 and RX1_2 only at one end thereof.

The touch sensing wirings RX1_1 to RX8_1 and RX1_2 may not be connected to the sensing detection patterns of the eighth and ninth sensing electrodes RE8 and RE9 that are opposite to each other (e.g., the second sensing detection pattern RE82 of the eighth sensing electrode RE8 and the first sensing detection pattern RE91 of the ninth sensing electrode RE 9). In addition, no wiring may be provided to connect the eighth sense electrode RE8 with the ninth sense electrode RE 9.

In addition, the touch sensing wirings RX1_1 to RX8_1 and RX1_2 may not be provided in the center area CA. Therefore, there may be no wiring connected to the eighth and ninth sense electrodes RE8 and RE9 in the central region CA.

The touch sensing wirings RX1_1 to RX8_1 connected to the ninth sensing electrode RE9 and the first to seventh sensing electrodes RE1 to RE7 may extend from the pad terminal unit TPA located at the lower side of the non-display area NDA toward the second side on the second direction dr2, and then may extend in the first direction dr1 on the outside of the right edge of the display area DA, and thus may be connected to the ninth sensing electrode RE9 and the right ends of the first to seventh sensing electrodes RE1 to RE7 (e.g., the second sensing detection pattern RE92 of the ninth sensing electrode RE9 and the sixth sensing detection patterns RE16 to RE76 of the first to seventh sensing electrodes RE 35 1 to RE 7). For example, the touch sensing wirings RX2_1 to RX8_1 may be connected to only end portions of the sixth sensing detection patterns RE16 to RE76 of the first to seventh sensing electrodes RE1 to RE7, respectively, and the touch sensing wiring RX1_1 may be connected to only one end of the second sensing detection pattern RE92 of the ninth sensing electrode RE 9.

The touch sensing wiring RX1_2 connected to the eighth sensing electrode RE8 may extend from the pad terminal unit TPA located at the lower side of the non-display area NDA toward the first side in the second direction dr2, then may extend in the first direction dr1 on the outer side of the left edge of the display area DA, and thus may be connected to the left end of the eighth sensing electrode RE8 (e.g., the first sensing detection pattern RE81 of the eighth sensing electrode RE 8). For example, the touch sensing wiring RX1_2 may be connected to only one end of the first sensing detection pattern RE81 of the eighth sensing electrode RE 8. In a case where the touch sensing wiring RX1_2 extends on the outer side of the left edge of the display area DA, the touch sensing wiring RX1_2 may extend on the inner side of the second touch driving wirings TX1_2 to TX5_ 2.

As described above, in the case where the touch sensing wirings RX1_2 and RX1_1 are arranged to be connected to the eighth and ninth sensing electrodes RE8 and RE9, respectively, the touch sensing wirings RX1_1 to RX8_1 and RX1_2 may be prevented from overlapping or crossing the touch driving wirings TX1_1 to TX5_1 and TX1_2 to TX5_ 2. Accordingly, the touch driving wirings TX1_1 to TX5_1 and TX1_2 to TX5_2 may be prevented from being short-circuited with the touch sensing wirings RX1_1 to RX8_1 and RX1_ 2.

In addition, the line widths of the touch driving wirings TX1_1 to TX5_1 and TX1_2 to TX5_2 can be easily controlled. If the line widths of the touch driving wirings TX1_1 to TX5_1 and TX1_2 to TX5_2 are increased, the recognition performance of the organic light emitting display device 1 may be improved. On the other hand, if the line widths of the touch driving wirings TX1_1 to TX5_1 and TX1_2 to TX5_2 are reduced, the touch ineffective space (dead space) of the organic light emitting display device 1 may be reduced.

In one exemplary embodiment of the present disclosure, two touch driving wirings may be connected to each first touch detection electrode IE1, and one touch sensing wiring is connected to each second touch detection electrode IE 2.

The voltage of the driving voltage signal supplied to the first touch detection electrode IE1 may be higher than the voltage of the driving voltage signal supplied to the second touch detection electrode IE 2. In the case where the driving voltage signal having a relatively high voltage is supplied to the first touch detection electrodes IE1, the voltage of each first touch detection electrode IE1 may vary significantly from one location to another according to the distance from the wiring connected to each first touch detection electrode IE 1. For example, if only the first touch driving wirings TX1_1 to TX5_1 are provided to be connected to only one end of each first touch detection electrode IE1, the voltage of the first drive detection pattern (e.g., the first drive detection patterns TE11 and TE21) of the first touch detection electrode IE1 may be significantly different from the voltage of the eighth drive detection pattern or the ninth drive detection pattern (e.g., the ninth drive detection pattern TE19 and the eighth drive detection pattern TE28) of the first touch detection electrode IE 1. By connecting a plurality of touch driving wirings to each of the first touch detection electrodes IE1, a difference between voltages of detection patterns of each of the first touch detection electrodes IE1 can be minimized.

Antistatic wirings ES1 and ES2 may be disposed on outer sides of the touch driving wirings TX1_1 to TX5_1 and TX1_2 to TX5_2 and the touch sensing wirings RX1_1 to RX8_1 and RX1_ 2. In one exemplary embodiment of the present disclosure, the antistatic wirings ES1 and ES2 may include a first antistatic wiring ES1 and a second antistatic wiring ES 2. The first and second antistatic wirings ES1 and ES2 may surround the touch driving wirings TX1_1 to TX5_1 and TX1_2 to TX5_2 and the touch sensing wirings RX1_1 to RX8_1 and RX1_2 in a ring-like manner. The first antistatic wiring ES1 and the second antistatic wiring ES2 may not be connected to each other.

The first antistatic wiring ES1 may cover a portion of the wiring disposed on the lower side and the right side of the display area DA.

The second antistatic wiring ES2 may cover the wirings provided on the other portion of the lower side, the left side, and the upper side of the display area DA.

The antistatic wirings ES1 and ES2 may be wirings through which the first reference voltage signal flows. The antistatic wirings ES1 and ES2 may mitigate electrostatic impacts that may be applied from the outside to the touch driving wirings TX1_1 to TX5_1 and TX1_2 to TX5_2, the touch sensing wirings RX1_1 to RX8_1 and RX1_2, and the detection electrode cells IE1 and IE 2.

The shield wirings GL1 to GL5 are disposed between the touch driving wirings TX1_1 to TX5_1 and TX1_2 to TX5_2 and the touch sensing wirings RX1_1 to RX8_1 and RX1_2 and/or between the touch driving wirings TX1_1 to TX5_1 and TX1_2 to TX5_2, the touch sensing wirings RX1_1 to RX8_1 and RX1_2 and the antistatic wirings ES1 and ES 2. The shield wirings GL1 to GL5 may include first to fifth shield wirings GL1 to GL 5.

The first shield wiring GL1 may be disposed between the touch sensing wirings RX1_1 to RX8_1 and the first antistatic wiring ES1, and the touch sensing wirings RX1_1 to RX8_1 and the first antistatic wiring ES1 all extend on the right side of the non-display area NDA.

The second shield wiring GL2 may be disposed between the first touch driving wirings TX1_1 to TX5_1 connected to the lower end of the first touch detection electrode IE1 and the touch sensing wirings RX1_1 to RX8_1 extending on the right side of the non-display area NDA.

The third shield wiring GL3 may be disposed between the first touch driving wirings TX1_1 to TX5_1 connected to the lower end of the first touch detection electrode IE1 and the touch sensing wiring RX1_2 extending on the left side of the non-display area NDA.

The fourth shield wiring GL4 may be disposed between the touch sensing wiring RX1_2 extending on the left side of the non-display area NDA and the second touch driving wirings TX1_2 to TX5_2 connected to the upper end of the first touch detection electrode IE 1.

The guard wirings GL1 to GL5 may be wirings through which the second reference voltage signal flows. The guard wirings GL1 to GL5 can prevent signal interference between each pair of adjacent wirings.

In one exemplary embodiment of the present disclosure, the pad terminal unit TPA may be disposed on a lower right side of the non-display area NDA. The position of the pad terminal unit TPA is not particularly limited and may vary depending on how the pad terminal unit TPA is electrically coupled to the touch member and other members. The pad terminal unit TPA may include pad terminals connected to the touch driving wirings TX1_1 to TX5_1 and TX1_2 to TX5_2, the touch sensing wirings RX1_1 to RX8_1 and RX1_2, the guard wirings GL1 to GL5, and the anti-static wirings ES1 and ES 2.

Hereinafter, a stacked structure of the touch member and how the touch member is coupled to other elements of the organic light emitting display device 1 will be described.
